  • One end of the pad is located close to the walls of the recess or space 19 in the cylinder, and the attachment between the pad and cylinder is usually made through the medium of screws, as shown in Fig. 6, although other means may be employed.
  • a bar 27, is secured to the cylinder in the recess 19 at that end contiguous to the pad;
  • this bar as shown particularly in Figs. 4: and 10 is provided with a series of pins 28, which pins extend through the bar, suitable apertures 29 being produced to receive them.

  • the springs are usually coiled around the pins and connected with them in such manner that the upper ends of the pins are normally held flush with the topsurface of the bar, and the lower ends a predetermined distance below the under surface of the bar, as shown in Fig. 4.
  • the pins maybe termed lift pins, since the portions of the sheet to be clamped rest upon the pins; and when that portion of the sheet is released from its clamp or clamps, the pins will be automatically acted upon, and will raise the said portion of the sheet from the cylinder, enabling it to pass freely to a table or other receptacle near the cylinder, as shown in-Fig. 10.
  • the pins are actuated through the medium of a series of fingers 31, located within the cylinder and secured upon a shaft 32, journaled in suitable bearings within the cylinder and extending usually from end to end of the latter.
  • An angle arm or cam 33 is secured preferably upon the left-hand end of the finger shaft 32, which end extends beyond the end of the cylinder, as shown in Figs. 5 and 6.
  • the angle arm or cam is brought in contact IIO lower ends of the lift pins, force the outer ends of the said pins outward and thereby lift the paper resting upon the pins, as shown in Fig. 10.
  • the angle arm or cam 33 has passed the stud 34, the fingers will gravitate to their normal position,and the pins being released will be returned by their springs to their normal position.
  • the clamp employed to hold the sheet to be treated consists of a plate 35, which is preferably of the same length as the pin-carrying bar 27, since the plate when in clamping position is supported at one edge by the said bar, and that surface of the bar upon which the plate is to rest is beveled, as shown at 36 in Figs. 7, 8 and 9.
  • the clamping plate is secured to a shaft 37, journaled in bearings 38, projected from the pin-carrying bar 27, the shaft and bar being parallel; and a pinion 39, is secured preferably to the left-hand end of the shaft.

  • the cross head may be termed a shifting head, as it is employed 'to effect a change in the position of the clamping plate.
  • One end of a rod 44 is eccentrically and pivotally connected with the shifting cross head, the attachment being made nearer one side edge, between the connection of the head with its shaft 41 and one of the forks, the fork 43, for example.
  • the rod 44 is held to slide in bearings 45, located upon the lefthand end of the cylinder, which end is wholly or partially closed; and a spring 47 encircles the rod between its bearings, and a collar 46 contained upon the rod, the spring being so attached to the rod as to cause the latter to exert constant pressure upon the shifting cross head in an outwardly direction.
  • the shifting cross head assumes two positions, both tangential to the cylinder. In one position the fork 43 is the outer one, and in gripped; and in the last named position the clamp will hold the sheet upon the pad.
  • the tension rod 44 acts to hold the shifting cross head in the inner position.
  • the shifting cross head 43 is acted upon by two studs 48 and 49, secured to the left hand extension 12 of the frame, one of the studs, that designated as 49, being located at the upper part of the frame extension upon a bracket 49, projected upward therefrom; and the other stud is placed near the lower end of the extension, as shown best in Fig. 6.
  • the lower stud 48 is in the vicinity of an adjustable section 50' of a feed table 50, the said feed table 50 being supported upon the frame by a cross bar 51, located upon the bed bars 13 of the frame, as shown in Fig. 3.
  • the upper stud 49 is located adjacent to a receiving table 0, and both studs extend horizontally from the extension of the frame in direction of the left-hand end of the cylinder.
  • the closing of the clamp takes place when the fork 43 of the shifting head is the outer one, taking the position formerly occupied by the fork 43"; and in this movement of the shifting cross head the tension rod will be thrown at the opposite side of the center of the said shifting head, and will therefore hold the head in its changed position.
  • the shifting cross head will remain in the position shown in Fig. 7, causing the clamping plate to hold the sheet until the sheet has received its coloring compound or coating, and also until the point is reached when the sheet is to be delivered to the receiving table 0, or removed from the cylinder. At this time the sheet is released from the clamp by the upper stud 49, entering the fork 43, which in the revolution of the cylinder will be the forward one, as shown in Fig. 8.
  • the cylinder As the cylinder continues to revolve it carries the pad 26 downward, facing the front of the machine; and when the end of the pad at which the bar ICO 27 is located approaches the adjustable section of the feed table the beveled portion 36 of the pin-carrying bar 27, will engage with the projecting portion of a second sheet, and at that instant the lower stud 48, will have acted upon the shifting cross head in such a manner as to close the clamp against the sheet, and another sheet is in position to be acted upon or coated, and to be released at the upper portion of the machine, or wherever the releasing trip 34 may be located.
  • the clamp being made in the nature of a blade will bear equally upon the entire surface of the paper with which it contacts; and the engagement of the clamp with the paper is such that it is an utter impossibility for the color, no matter how thin, to find its Way at the back of the sheet, and in this manner the sheet at its backis preserved clean, and may in its turn be coated or colored if desired.
  • the feed table is provided with the movable section 50 in order that the said section may carry the paper upward to meet the beveled surface 36 of the lift-pin bar.
  • a shaft 52 Beneath the movable section 50 of the feed table a shaft 52, is located in the frame, and the said shaft has claws 53 mounted upon it, adapted for engagement with the under surface of the said movable section of the table; and an angular guide 54, is projected from the opposite side of the shaft, that is, in direction of the cylinder, the guide being preferably made integral with or attached to the claws, both moving together.
  • a pitman 55 is attached to the claws where the latter are mounted upon the shaft 52, the said pitman being shown best in dotted lines in Fig. 4. This pitman carries at its rear end a friction roller 56, which is adapted to be acted upon by a cam 57, carried by the cylinder shaft 15.
  • the claws When the pitman 55 is in an upper position, being carried to that position by a spring or equivalent tension device, not shown, the claws will be removed from contact with the feed table, as shown in Fig. 11, and the movable section 50 of the table will be in a downwardly inclined position, while the guide 54 connected with the claws will be elevated in front of the rear end of the movable section of the table, extending above its uppersurface. Therefore when a sheet is placed upon the table it is fed rearward or in direction of the cylinder until the sheet strikes the guide 54, as is, likewise shown in Fig.
  • a table 58 is pivotally connected with the rear portion of the rear standards 12 of the frame, and the said table is provided with an arm 59, shown in Fig. 3, which extends downward and is connected with a horizontal arm 60, the said arm extending within the body of the frame, and is held to slide upon a suitable support 61 located preferably upon the left-hand bottom bar 14 of the frame, since the operator usually stands at this side of the machine in feeding.
  • a treadle 62, carrying a cam 63 is pivotally mounted through the medium of said cam, upon a shaft 64, also shown in Fig. 3. The cam is flattened at one side, the remaining exterior surface being cylindrical, and the cam is adapted for engagement with the arm 60.
  • the table 58 When the flat surface of the cam is in engagement with the arm 60, the table 58 will drop downward a predetermined distance, and when the cylindrical surface of the cam engages with the inner end of the arm 60 the tablewill be carried upward in direction of the cylinder, the cam holding the table in whatever position it may be placed. Any desired means may be employed for limiting the downward movement of the table, or it may have support. other than that provided by the cam.

  • Both the take-up and distributing rollers are driven from the cylinder, and the driving connection is effected in the following manner:
  • a bracket 75 preferably of angular construction, is projected forwardly from the right-hand end of the color box 65.
  • This bracket is provided with three pinions designated respectively as 76, 77 and 78.

  • Brushes F are employed to travel over the coated or colored paper and facilitates the distribution of the color thereon. These brushes may be of any approved construction and are reciprocated over the cylinder in direction of its ends. Four brushes are illustrated, but any desired number may be used, and they are located at intervals between a point at the upper front portion of the cylinder and a point above the color-applying mechanism E, as is bestshown in Fig. 4.. Two opposing slide-ways 81, are employed in connection with each brush, and the said slide-ways are secured to the extensions 12 of the frame and project beyond the cylinder.

LOUIS DEJONGE, in, or STAPLETON, NEW YORK.
MACHINE FOR COATING PAPER OR LIKE MATERIAL IN SHEETS AND DRYING SAME.
SPECIFICATION forming part of Letters Patent No. 533,443, dated February 5, 1895.
Application filed January 31, 1894. Serial No. 498,578. (No model.)
To all whom it may concern.-
Be it known that I, LOUIS DEJONGE, Jr., of, Stapleton, in the county of Richmond and State of NewYork, have invented certain new and useful Improvements in Machines for Coating Paper or Like Material in Sheets and Drying the Same, of which the following is a full, clear, and exact description.
My invention relates to a machine for coloringor coating sheets ofpaper, or like material, and likewise a machinewhereby the colored or coated sheets may'be dried.
The object of the invention is to provide a machine wherein sheets of paper or like material will be automatically clamped to a carrier, conveyed to the color-carrying and applying mechanism, held from buckling when coated, automatically released from the car rier at a given point in its travel, and automatically elevated when released, whereby the colored and coated sheets may be mechanically removed from the carrier.
A further object of the invention is to provide a machine wherein wet sheets may be automatically removed from the coloring or coating section and made to travel through any desired number or runs, even when one run is above or beneath the other, the travel through the runs being accomplished automatically, the sheets hanging in a pendent position throughout the entire drying operation.
Another object of the invention is to so construct the carriages or conveyors for the sheets that they may be arranged close to gether without interfering one with the other, and to provide a clip for the carriages or conveyers which will not injure the sheets as they automatically grip them, and fromwhich the sheets may be conveniently and expeditiously released.
Another object of the invention is to provide a means whereby when the sheets are removed from their carriages or conveyers, the latter will be automatically directed to the coloring or coating section of the machine and automatically receive another sheet or sheets to be dried; and a final object of the invention is to provide for the coating and the drying of the sheets without in the least marring the uncoated surface if the coating is upon one side only.
The invention consistsin the novel construction and combination of the several parts, as will be hereinafter fully set forth,
and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.
Figure 1 is a side elevation of the coloring machine, and a side elevation of one end of the drier. Fig. 2 is aside elevation of the drier, showing both the front and rear ends thereof, the central portion being broken away. Fig. 3 is an enlarged side elevation of the coloring section of the machine. Fig. 4 is an enlarged cross section of the cylinder adapted to carry the paper to be colored, the section being likewise taken through the distributing brushes and through the color-applying mechanism. Fig. 5 isa section taken practically on the line 55 of Fig. 6, representing one end portion of the cylinder and adjacent mechanism, and illustrating in particular the mechanism for holding the ends of the sheet to be colored to the cylinder. Fig. 6 is a front view of the mechanism shown in Fig. 5. Fig. 7 is a view similar to that shown in Fig. 5, showingthe paper held fast to the drum by the clamping mechanism, Fig. 5 representing the clamp open to receive the sheet. Fig. 8 is a view similar to Figs. 5 and 7, illustrating the clamp in contact with the sheet,
and the trip mechanism nearing the point at which the sheet is to be released. Fig. 9 is a view similar to Fig. 8, illustrating the shifting mechanism as having been operated upon, the clamp removed from the sheet, and the sheet lifted at the end formerly clamped. Fig. 10 is a sectional view of the cylinder as represented in Fig 9, illustrating in detail the lifting device for the paper. Fig. 11 is aperspectiveview illustrating how the conveyer or carriage sticks adapted to carry the colored sheets are transferred from one run to the other in the drying section of the machine. Fig. 12 is a plan view of the coloring section of the machine, and a portion of the drying section adjacent to the coloring section, being practically a plan view of that portion of the machine shown in Fig. 3. Fig. 13 is a sectional detail view, illustrating the manner in which the clips of the stick carriage or conveyer are opened to receive the ends of the paper after the paper has been colored and is leaving the machine. The said view shows also in dotted lines the clips in a closed position, grasping the ends of the sheet and traveling upward to the drying section. of the machine and removing the sheet from the coloring section thereof, and the section is taken on the line 13-13 of Fig. 12. Fig. 14 is a detail view of the conveyer or carriage sticks, illustrating the same as traveling upward to the drier section, and the clip of the stick in a horizontal position, the sheet being nearly removed from the coloring section of the machine. Fig. 15 is a longitudinal section of one end of the conveyer or carriage stick. Fig. 16 is an end View of the drying section of the machine, said view being made upon a large scale. Fig. 17 is a longitudinal vertical section of the drying section of the machine, taken practically on the line 1717 of Fig. 16. Fig. 18 is a longitudinal vertical section of what may be termed the rear end of the drier, or the end opposite that illustrated in Figs. 16 and 17; and Fig. 19 is a detail view, showing a portion of the main conveyer of the drying section of the machine, and a stick carriage or conveyer in section upon the main conveyer. Fig. 20 is a perspective view illustrating the manner in which the carrier sticks are guided upward duringthe time of receiving and after they have received the colored sheets. Fig. 21 is a detail view partially in side elevation and partially in section of one of the carrier sticks, illustrating a slight modification in the construction of the clips; and Fig. 22 is a transverse section through the stick and through one of the clips.
I will first describe the construction and operation of the mechanism employed for coloring or coating the paper, next the mechanism for drying the same, and finally the connection between the coloring and drying mechanisms.
In the matter of the coloring mechanism, a hollow cylinder A, is mounted to revolve in a frame B. The frame may be of any desired shape, but as illustrated it consists of front standards 11 and rear standards 12 joined together. The standards of each set are connected by suitable cross bars or tie rods, and the two sets of standards are usually connected by an upper side or bed bar 13, ordinarily located at or near a central point between the ends of the standards and a bottom side bar 14. The shaft 15 of the cylinder A, is journaled in bearings 16, carried by the rear set of standards above the bed bar, best shown in Fig. 3, and the ends of the cylinder are in a measure closed or protected by segmental extensions 12 of the rear standards. The cylinder preferably consists of a metal body 17, securely attached to the shaft 15, and a facing 18 of wood, papier-maeh or equivalent material; but atone point in the circumference of the cylinder the casing is cut away from end to end, producing a recess or space 19. The cylinder is revolved by producing or locating a gear 20 at for example its righthand end, which gear meshes with a pinion 21, upon a drive shaft 22, journaled in the rear standards of the frame. A driving pulley 23, is shown as secured to the right-hand end of the drive shaft to be connected by means of a belt 24 with any source of power. A second and larger pulley 25, is located at the opposite end of the shaft, adapted to drive portions of the mechanism, usually distributing brushes.
A pad 26 of rubber or equivalent material is made to cover a portion of the outer or circumferential face of the cylinder, and is removably secured to said surface. The pad is adapted as a bed or platen forthe sheet to be colored, and consequently is of sufficient size to support the entire surface of the sheet to be operated upon. The pad, although shown as extending to the end of the drum may terminate at any desired distance from the end. One end of the pad is located close to the walls of the recess or space 19 in the cylinder, and the attachment between the pad and cylinder is usually made through the medium of screws, as shown in Fig. 6, although other means may be employed. A bar 27, is secured to the cylinder in the recess 19 at that end contiguous to the pad;
and this bar, as shown particularly in Figs. 4: and 10 is provided with a series of pins 28, which pins extend through the bar, suitable apertures 29 being produced to receive them. The apertures are made wide enough between their ends to form chambers for the reception of springs 30. The springs are usually coiled around the pins and connected with them in such manner that the upper ends of the pins are normally held flush with the topsurface of the bar, and the lower ends a predetermined distance below the under surface of the bar, as shown in Fig. 4.
The pins maybe termed lift pins, since the portions of the sheet to be clamped rest upon the pins; and when that portion of the sheet is released from its clamp or clamps, the pins will be automatically acted upon, and will raise the said portion of the sheet from the cylinder, enabling it to pass freely to a table or other receptacle near the cylinder, as shown in-Fig. 10. The pins are actuated through the medium of a series of fingers 31, located within the cylinder and secured upon a shaft 32, journaled in suitable bearings within the cylinder and extending usually from end to end of the latter. An angle arm or cam 33, is secured preferably upon the left-hand end of the finger shaft 32, which end extends beyond the end of the cylinder, as shown in Figs. 5 and 6.
When the clamped portion of the sheet arrives at the point at which the sheet is to be discharged, and just after the clamping mechanism employed is removed from the sheet,
the angle arm or cam is brought in contact IIO lower ends of the lift pins, force the outer ends of the said pins outward and thereby lift the paper resting upon the pins, as shown in Fig. 10. When the angle arm or cam 33 has passed the stud 34, the fingers will gravitate to their normal position,and the pins being released will be returned by their springs to their normal position.
It will be understood that any desired number of pins may be employed, and that a finger 31 is provided for each pin; also that any equivalent of the angle arm or cam 33 and the stud 34 may be substituted therefor.
The clamp employed to hold the sheet to be treated consists of a plate 35, which is preferably of the same length as the pin-carrying bar 27, since the plate when in clamping position is supported at one edge by the said bar, and that surface of the bar upon which the plate is to rest is beveled, as shown at 36 in Figs. 7, 8 and 9. The clamping plate is secured to a shaft 37, journaled in bearings 38, projected from the pin-carrying bar 27, the shaft and bar being parallel; and a pinion 39, is secured preferably to the left-hand end of the shaft. The pinion 39 meshes with a second pinion 40, secured upon the inner or right-hand end of a short shaft 41, journaled in bearings located upon the body of the cylinder in the recess 19. The left-hand end of the shaft 41 extends some distance beyond the end of the cylinder, as shown in Fig. 6, being securely fastened to the central portion of a cross head 43, having forked or bifurcated extremities, designated respectively as 43 and 43 The cross head may be termed a shifting head, as it is employed 'to effect a change in the position of the clamping plate.
One end of a rod 44, is eccentrically and pivotally connected with the shifting cross head, the attachment being made nearer one side edge, between the connection of the head with its shaft 41 and one of the forks, the fork 43, for example. At its opposite end and intermediate of its ends the rod 44, is held to slide in bearings 45, located upon the lefthand end of the cylinder, which end is wholly or partially closed; and a spring 47 encircles the rod between its bearings, and a collar 46 contained upon the rod, the spring being so attached to the rod as to cause the latter to exert constant pressure upon the shifting cross head in an outwardly direction.
The shifting cross head assumes two positions, both tangential to the cylinder. In one position the fork 43 is the outer one, and in gripped; and in the last named position the clamp will hold the sheet upon the pad. The tension rod 44 acts to hold the shifting cross head in the inner position.
The shifting cross head 43, is acted upon by two studs 48 and 49, secured to the left hand extension 12 of the frame, one of the studs, that designated as 49, being located at the upper part of the frame extension upon a bracket 49, projected upward therefrom; and the other stud is placed near the lower end of the extension, as shown best in Fig. 6. The lower stud 48 is in the vicinity of an adjustable section 50' of a feed table 50, the said feed table 50 being supported upon the frame by a cross bar 51, located upon the bed bars 13 of the frame, as shown in Fig. 3. The upper stud 49, is located adjacent to a receiving table 0, and both studs extend horizontally from the extension of the frame in direction of the left-hand end of the cylinder.
In the operation of the clamping plate 35, supposing the plate to be in the open position shown in Fig. 5, which figure represents the cylinder nearly ready to receive the sheet of material to be coated and which sheet is designated as D, the stud 48, will at that time have entered the fork 43 of the shifting cross head. As the cylinder revolves in the direction of the arrow in Fig. 5, the inner fork 43*, or that engaged by the fixed stud 48, will be carried forward and the shifting pinion 40 will be turned in a direction to so move the clamping pinion 39 that the clamping plate will be forced upon the sheet D if the latter is fed to the beveled surface 36 of the pin bar 27, as shown in Fig. 7. The closing of the clamp takes place when the fork 43 of the shifting head is the outer one, taking the position formerly occupied by the fork 43"; and in this movement of the shifting cross head the tension rod will be thrown at the opposite side of the center of the said shifting head, and will therefore hold the head in its changed position. The shifting cross head will remain in the position shown in Fig. 7, causing the clamping plate to hold the sheet until the sheet has received its coloring compound or coating, and also until the point is reached when the sheet is to be delivered to the receiving table 0, or removed from the cylinder. At this time the sheet is released from the clamp by the upper stud 49, entering the fork 43, which in the revolution of the cylinder will be the forward one, as shown in Fig. 8. As the stud 49 acts upon the fork 43 by the revolution of the cylinder, the shifting head is rocked until the fork 43 is brought to the upper position and the fork 43 to the lower position, as shown in Fig. 9, and the clamp shaft is rocked in a direction to remove the clamp from the sheet, this position of the shifting head corresponding practically to its position at starting and shown in Fig. 5. As the cylinder continues to revolve it carries the pad 26 downward, facing the front of the machine; and when the end of the pad at which the bar ICO 27 is located approaches the adjustable section of the feed table the beveled portion 36 of the pin-carrying bar 27, will engage with the projecting portion of a second sheet, and at that instant the lower stud 48, will have acted upon the shifting cross head in such a manner as to close the clamp against the sheet, and another sheet is in position to be acted upon or coated, and to be released at the upper portion of the machine, or wherever the releasing trip 34 may be located. The clamp being made in the nature of a blade will bear equally upon the entire surface of the paper with which it contacts; and the engagement of the clamp with the paper is such that it is an utter impossibility for the color, no matter how thin, to find its Way at the back of the sheet, and in this manner the sheet at its backis preserved clean, and may in its turn be coated or colored if desired. The feed table is provided with the movable section 50 in order that the said section may carry the paper upward to meet the beveled surface 36 of the lift-pin bar.
Beneath the movable section 50 of the feed table a shaft 52, is located in the frame, and the said shaft has claws 53 mounted upon it, adapted for engagement with the under surface of the said movable section of the table; and an angular guide 54, is projected from the opposite side of the shaft, that is, in direction of the cylinder, the guide being preferably made integral with or attached to the claws, both moving together. A pitman 55, is attached to the claws where the latter are mounted upon the shaft 52, the said pitman being shown best in dotted lines in Fig. 4. This pitman carries at its rear end a friction roller 56, which is adapted to be acted upon by a cam 57, carried by the cylinder shaft 15. When the pitman 55 is in an upper position, being carried to that position by a spring or equivalent tension device, not shown, the claws will be removed from contact with the feed table, as shown in Fig. 11, and the movable section 50 of the table will be in a downwardly inclined position, while the guide 54 connected with the claws will be elevated in front of the rear end of the movable section of the table, extending above its uppersurface. Therefore when a sheet is placed upon the table it is fed rearward or in direction of the cylinder until the sheet strikes the guide 54, as is, likewise shown in Fig. 11; and prior to the action of the clamping plate 35 to clamp the sheet, the cam 57 will have depressed the pitman 55 and thus elevated the claws, depressing the guide 54 and elevating the rear end of the movable table section, leaving the sheet extending beyond the rear end of that section to be caught by the clamping plate.
Beneath the cylinder A a table 58, is pivotally connected with the rear portion of the rear standards 12 of the frame, and the said table is provided with an arm 59, shown in Fig. 3, which extends downward and is connected with a horizontal arm 60, the said arm extending within the body of the frame, and is held to slide upon a suitable support 61 located preferably upon the left-hand bottom bar 14 of the frame, since the operator usually stands at this side of the machine in feeding. A treadle 62, carrying a cam 63, is pivotally mounted through the medium of said cam, upon a shaft 64, also shown in Fig. 3. The cam is flattened at one side, the remaining exterior surface being cylindrical, and the cam is adapted for engagement with the arm 60. When the flat surface of the cam is in engagement with the arm 60, the table 58 will drop downward a predetermined distance, and when the cylindrical surface of the cam engages with the inner end of the arm 60 the tablewill be carried upward in direction of the cylinder, the cam holding the table in whatever position it may be placed. Any desired means may be employed for limiting the downward movement of the table, or it may have support. other than that provided by the cam.
The table 58 is adapted to support the colorcarrying and applying mechanism, and if desired the table may be made removable from the frame.
The color-carrying and applying mechanism in its entirety is designated by the reference letter E, and is best shown in Figs. 3 and 4. It comprises the following parts: A color box 65, provided with a double bottom forming a steam space 66, is located upon the table and adj ustably connected therewith by means of a set screw 67, or an equivalent fastening device. A take-up roller 68, of any approved construction, is held to turn in the color box 65, and it may here be remarked that the color box is practically of the same length as the cylinder. Hangers 69, are pivoted upon the trunnions of the take-up roller 68, or upon an equivalent support, one hanger extending upward from each end of the color box, as shown in dotted lines in Fig. 4 and in positive lines in Fig. 3. Each hanger is provided at its upper end with a sliding box and an adjusting mechanism 71, whereby the box may be raised or lowered and held in its adjusted position. The trunnions of the dis tributing roller 72, are journaled in the said boxes 70, and the distributing roller is preferably of less diameter than the take-up roller, and the two are adapted to run in more or less close contact. The distributing roller is held in position to bear to a greater or less degree upon the sheet to which the color is to be applied, preferably through the medium of guide arms 73, having bearing against the hangers 69 of the distributing roller, said guide arms being screwed into brackets 74 attached to the rear end portions of the table 58, as shown in Fig. 4. The arms 73 are rendered adjustable through the medium of nuts located at their inner ends. The hangers 69 are held against their guide arms 73 by springs 73" attached to the upper portion of the hangers and to the corresponding portions of the brackets 74 being secured to said brackets by adjusting screws 74, and the attachment between the springs and the adjusting or take-up screws is a removable one; but I desire it to be distinctly understood that other means may be substituted for regulating the tension between the distributing roller and the paper than those shown, although the spring and adjusting device illustrated are preferred owing to their simplicity and effectiveness.
Both the take-up and distributing rollers are driven from the cylinder, and the driving connection is effected in the following manner: A bracket 75, preferably of angular construction, is projected forwardly from the right-hand end of the color box 65. This bracket is provided with three pinions designated respectively as 76, 77 and 78. The pinion 78 meshes with the gear 20 ofthe cylinder and with the pinion 77; and the pinion 76 meshes with the pinion 77 and with a gear 79, formed preferably upon the right-hand end of the take-up roller 68, while the gear on the take-up roller meshes with a corresponding gear 80, located upon the distributing roller.
It will be observed that the entire colorapplying device may be dropped at any time out of engagement with the cylinder by the manipulation of the treadle 62, and all that it carries may be adjusted to or from the cylinder as desired, and that the distributing roller may be adjusted to or from the take-up roller, and the distributing roller adjusted independently of other adjustments to or from the pad of the cylinder.
Brushes F, are employed to travel over the coated or colored paper and facilitates the distribution of the color thereon. These brushes may be of any approved construction and are reciprocated over the cylinder in direction of its ends. Four brushes are illustrated, but any desired number may be used, and they are located at intervals between a point at the upper front portion of the cylinder and a point above the color-applying mechanism E, as is bestshown in Fig. 4.. Two opposing slide-ways 81, are employed in connection with each brush, and the said slide-ways are secured to the extensions 12 of the frame and project beyond the cylinder. Each opposing pair of slide ways is connected by rods 82, and each slide-way is provided with a box 83, held to slide therein each box being fitted with an adjusting screw 84, or its equivalent as shown in Fig. 3. A head block 85, preferably of angularconstruction is located near the inner side of each box 83, see Figs. 4 and 12; and each head block has secured to its vertical member two rods 86, which rods pass loosely through openings in adjacent boxes 83, whereby the head blocks have lateral sliding movement in their boxes. Opposing head blocks are connected by cross bars 87, attached to the horizontal members of the latter; and posts 88 are ordinarily used to attach the backs of the brushes at their ends to the corresponding portion of the cross bars. When four brushes are employed they preferably derive movement from two pulleys 89 and 90, located upon the left-hand side of the machine, one pulley between each two slide-ways as shown in Fig. 3. These pulleys are carried by standards 91, represented as attached to the left-hand extensions 12 of the frame. The pulleys 89 and 90, are driven by a large driving pulley 25 connected with them by.-a belt 92, and each pulley 89 and 90, is virtually a crank disk, since each carries upon its inner face an eccentrically located pin 93, as is best shown in Fig. 12. The driving connection between the pulleys and the brushes is effected by mounting upon each left-hand slide-way 81 a lever 94 of the angle or elbow type, and connecting one arm of each lever, by means of a rod 95, with the cross bar 87 of one of the brush-carrying frames. See Fig. 12. The opposite end of each lever 94: is connected by a link 96 with one of'the crank pins 93, two links belonging to adjoining brushes being connected with each crank pin, whereby adjoining brushes will be reciprocated simultaneouslyin opposite directions.
It is very desirable that the sheets, after they have received their coating, or have been colored, should be kept straight and flat upon the cylinder pad to prevent them from buckling. To that end I locate boxes 97 between the slide-ways 81, as shown in Figs. 3 and 4:, journal shafts 98 in said boxes, and secure friction wheels 99 upon the shafts in an adjustable manner. The wheels 99, are adapted to travel upon the sheets at or near their side edges, as more or less of a margin is always allowed.
With reference to the drying section of the machine, the body thereof consists of a frame of any desired length or width. Usually however, it is quite narrow or of comparatively great length. The frame is alike in construc tion on both sides, and as shown in the drawings consists of two spaced forward posts 100 and 101, extending from the door to the ceiling or roof of an apartment, two similar intermediate posts 102 and 103, and a rear end post 105, having attached to its inner face an angular guide bar, producing a longitudinal channel 104*, Fig. 18. A guide bar 106, preferably L- shaped in cross section, extends from the inner front posts of the frame to the inner one of the rear posts, being located a predetermined distance from the ceiling and attached to the inner faces of the posts. The two bars 106 constitute the upper run. The nextlower run is shorter and consists of like guide bars 107, similarly secured but extending from the front post to the forward of the intermediate posts only, as shown in Fig. 2. The third and lower run is constructed of bars 108, shaped and secured in the same manner and practically the same length as the guide bars 107 and located beneath the latter guide bars, while a fourth run, constructed of guide bars lIO 109 shaped like the other pairs is located at the bottom of the frame and extends from end to end thereof.
In the form of drier illustrated the three upper runs are intended for drying purposes, and the lowest for returning the sticks or other medium employed to carry the articles to be dried to the front of the drying section, from whence they are conveyed in a manner to be hereinafter described to the coloring section of the machine from which section they were taken.
An endless conveyer 110, travels over the horizontal members of the guide bars 106 of the upper run, one stretch of the conveyor resting upon said members, the other stretch being beneath them, as shown in Fig. 2. -At the forward end of the upper guide bars 106, sprocket wheels 111, are located, supported by suitable hangers, and corresponding sprocket wheels 112, are located at the rear ends of said bars, being secured to shafts 113, journaled in the frame, which shafts carry gear wheels 114 at their outer ends. The conveyers 110, which are preferably constructed of endless chain belts, run over the said sprocket wheels, and the links of the chain are provided at predetermined intervals with pins or studs 115, standing at right angles to the links and in an upright position when the chains are upon the guide bars 106. The conveyer116 of the next lowest run and which travels over the guide bars 107, is made preferably in two sections 116 and 116 The section 116% is the longest section, and is made to pass over a sprocket wheel 117, one of which isjournaled at the inner end of each guide bar 107.
The section 116 of each conveyer116, is made to pass over a second sprocket wheel 118, shown in dotted lines in Fig. 2, which sprocket wheel is fast upon a shaft 119, and the said shaft carries likewise a gear wheel 120. The shafts 119, are journaled in the frame near the inner posts 101 of the forward sets. One of the shafts 119, preferably the left-hand one, is also provided with a small pulley 121, and both of the shafts are provided in addition to the sprocket wheels 118, with a second sprocket wheel 122, as shown in Fig. 17. These additional sprocket wheels 122, receive one end of the shorter section 116 of the conveyers 116, and the opposite end of this section of the conveyers passes over a sprocket wheel 123, jonrnaled upon a hanger 124 projected from the forward portion of the frame, as is likewiseshown in Fig. 17, in which view also an idle sprocket 125 is shown as engaging with the lower stretch of this section of the conveyor at or about its center, the idle sprocket being journaled upon a bracket 126, projected from the inner forward post 101. The idle sprocket wheel, and likewise the sprocket wheel 123, appear upon both sides of the frame. The guide bar 107 of this second run at its forward end is somewhat inclined for the purpose of communicating with a transfer mechanism F through the medium of which the material carried by the conveyers 116, is conveyed to the upper conveyers 110.
The transfer mechanism F3, is duplicated at each side of the machine as well as the conveyers; and at each side of the machine, between the forward ends of the upper conveyers 110 and the next lower conveyers 116, hangers 127 are projected rearwardly from the forward posts or standards 1 00, and each hanger journals a shaft 128, and each of said shafts has mounted upon its outer end a gear wheel 129, while a lifting or transfer arm 130, is secured about centrally upon the inner end of each of the shafts 128. Each transfer arm is provided with a recess at each end, the recesses facing in opposite directions, one of them being designated as 131 and the other as 132.
A track 133, is secured upon the upper or horizontal section of the forward portion of each guide beam 107 of the second run-way, and the said tracks 133, are curved forwardly and upwardly in the segment of a circle, being secured to the inner faces of the front uprights 100, and the upper ends of the tracks 133 are carried over and upwardly beyond the forward path of the upper stretch of the upper conveyers 110, as shown best in Fig. 17, while a second track 134, is projected from the inner face of each front standard or upright 100, concentric with the upper portion of the outer track 133, the rear end of the shorter track 134 being carried alongside of the sprocket wheels 111 supporting the forward ends of the conveyers 110. Thus whatever is carried by the lower conveyers 116 to the track 133, will by the revolution of the transfer arm 130 be carried upward, as shown in Figs. 11 and 17, in engagement with the track 133 until the space between the tracks 134 and 133 is reached, whereupon the article carried will then be supported by the lower and shorter track 134, until it can be received upon the upper stretch of the upper conveyers 110. It may here be observed that instead of transfer arms being employed to ac complish this transfer from one run to the other, endless belts may be substituted if in practice it is found desirable, or any equiva' lents of the belts may be employed.
. The drive shaft 135 of the drier is held to turn in bearings 136, preferably projected downward from the ceiling or an overhead support, and the drive shaft extends across the upper run from one side of the machine to the other, being provided at one end with a pulley 137, which pulley is connected by a belt 138 with a main driving shaft 139, provided with a suitable pulley to receive the belt, and likewise a pulley to receive the belt 24 communicating motion to the coloring machine and above alluded to. .At the opposite end of the driving shaft 135 a smaller sprocket wheel 140 is secured, and the said sprocket 140, is connected by a link belt 141 with a sprocket 142, secured preferably upon the left-hand end of a shaft 143, which extends from one side of the machine to the other above the second run, or the one next to the top. In Fig. 2 this shaft is shown as being supported upon the guide beams 107, while in Fig. 17 it is shown as being journaled in bearings attached to a third forward upright orstandard 100 Either construction may be adopted. The shaft 143 carries at each of its ends a pinion 144, and these pinions mesh with the gears 120, carrying the sprocket wheels over which both sections of the conveyers 116 pass, and in this manner proper movement is given to both sections of the conveyers.
The shaft upon which the left-hand wheel 120, is secured has been described as being provided with a small sprocket 121. This sprocket 121 carries a link belt 145, which likewise passes over a small sprocket 146, which sprocket is secured upon the left-hand end of a shaft 147, journaled upon the forward upper portion of the frame, as shown in Figs. 2 and 17; and the shaft 147 extends from side to side of the machine. The shaft carries at each end a gear 148, and the gears mesh with the gears 129 of the forward transfer mechanism.
A third couveyer 149, is held to travel beneath the conveyer 116, upon and under each of the guide bars 108. In the drawings these conveyers 149, are the receiving conveyers, being adapted to take the article to be dried from the coloring machine. The conveyers 149, are each constructed in two sections, a
long or forward section 149, and a short or rear section 149 The forward section of each conveyer 149 travels over a sprocket wheel 150, journaled in the front of the machine, while the rear ends of the sections travel over sprocket wheels 151, shown in .dotted lines in Fig. 2 upon a shaft 152 located near the forward of the intermediate stand ards or uprights 102. Upon the same shafts 152 which carry the sprocket wheels 151, a second sprocket wheel 153 is secured at each side, and over these second sprocket wheels the forward ends of the shorter conveyor sections 149 pass, the rear end of each of these sections being passed over sprocket wheels 154, journaled upon hangers usually attached to the rear intermediate uprights 103,as shown in both Figs.2 and 18, while an idlersprocket wheel 155, engages with the lower stretch of each conveyer section, and the upper stretch is given somewhat of an upward and a rearward inclination. This inclination is given in order to meet another transfer mechanism F, by means of which the material carried by the conveyers 149, may be elevated to the next upper conveyer 116. This transfer mechanism is substantially identical with that which has been heretofore described. It consists of two shafts 156, located one at each side of the frame and journaled in hangers secured to the upright 103. Each shaft 156 carries upon its inner end a transfer arm 157,
.provided with oppositely-facing recesses 158 upwardly and forwardly curved segmental track 161, connects with the rear end of each guide bar 108, and is carried upward above the supporting surface of the next upper guide bar 107, as shown in Fig. 18; and asec- 0nd and concentric track 162, is attached to the inner face of each upright 103, the smaller tracks extending forwardly to meet the rear end of the conveyers 116 near which it is located. Thus in the operation of the machine the arms 157 will receive the materialcarried rearward by the conveyers 149 and will transfer said material to the conveyers 116 of the next run, and from that run the forward transfer mechanism F will convey the material to the conveyers of the next run. Both sectious'of the lower conveyor 149 and the rear transfer mechanism receive movement from the drive shaft 135. To that end shafts 164, are journaled at each side of the machine, carrying gears 165, meshing with the gears 159 on the shafts 156. The shafts 164 are likewise provided with sprocket wheels 166, each adapted to carry a belt 163, which belts run over sprocket wheels 160 located upon the rear shafts 152 of the lower conveyers 149; and both of said shafts 152, are provided with a gear 160", which gears mesh with pinions 160, located at opposite ends of a shaft 160, extending from side to side of the machine. The shaft 160 is driven by a link belt 167, driven by the main shaft 135, and passed over a sprocket wheel at the left hand end of the shaft 160 as shown in Fig. 2.
Shafts 168, are journaled in the lower rear portion of the frame at each side, and a vertical conveyer 169, is passed over sprocket wheels 170 located upon the shafts 168, and over sprocket wheels 171, located upon the upper shafts 113, which likewise carry the sprocket wheels supporting the rear portion of the upper conveyers. The rear stretches of the vertical conveyers 169, face the grooves 104 in the sides of the rear portion of the machine; and the upper conveyers 110, and the vertical rear conveyers 169, are driven by the same mechanism and in the following manner: A line shaft 172, is located at about the rear central portion of the frame. This shaft carries a large pulley 173, and asmaller pulley adjacent to the larger one, as shown in Figs. 2 and 18. The larger pulley 173 is connected with the left-hand pulley 160 on the left-hand transfer shaft 156 by a belt 174, while the smaller pulley adjacent to the pulley 173 is connected with a larger pulley 176 by a belt 175, as shown in Fig. 2, and said pulley 176 is journaled upon ashaft or in bearings below the line shaft 17.2. The
pulley 176 carries a smaller pulley 177, which is connected by a belt 178, with a pulley 179 located on a shaft 180, which extends from side to side of the machine at its upper rear is likewise provided with a pulley 160. An
portion, over the upper rear gears 114; and the said shaft 180, carries two pinions, one near each end,'which mesh with the said gears 114, and thereby impart movement to the upper shaft 113, carrying the supports for the rear end of the upper conveyer and the upper end of the rear vertical conveyer.
The conveyers are all constructed in the manner heretofore described; that is, with a series of pins 115 projecting from them, and all of the conveyers heretofore described move at the same rate of speed.
The material carried by the upper conveyers is to be removed from the sticks, or whatever carrier is employed, before the carriers reach the rear vertical conveyer; and to that end a platform 181, shown in Fig. 18, is erected at the rear portion of the machine within the frame, and upon which the operator may stand and remove the sheets D from the carriage. The vertical conveyers will then conduct the carriers downward, the carriers being guided in their downward movement through the medium of the grooves 104, and will deliver the carriers to the return conveyor 182, traveling over the lower guide bars 109 from front to rear of the frame. The return conveyers 182, are alike in construction to the convey ers heretofore described, but they have the same speed as the machine to which they are to deliver the article carried by them.
The lowermost conveyers 182 travel over sprocket wheels 183 located at the rear of the machine, and over like wheels located at the lower forward portion of the machine upon a shaft 184, which shafts likewise carry sprocket Wheels 185, supporting conveyers 186, serving to establish a return connection between the conveyers 182 and the coloring machine.
It is necessary, in the event the carriers or sticks shouldbecome diagonally located on the upper conveyers 110, that they should be straightened before they are received by the vertical conveyers 169; and to that end, as shown in Fig. 19, the upper guide bars 106, are provided near their rear ends with a cam plate 187, and when a stick reaches these plates, the end that touches a plate first will remain at the plate until the opposite end has been forced against the corresponding plate, and the fingers 115 of both of the upper conveyers are in engagement with the stick, whereupon the fingers will force the stick upward over the cam plates, carrying them down again upon the guide bars 106 to be received by the descending fingers of the vertical elevator, and when so received the ends of the stick will enter the guide grooves 104.
The preferred form of carrier is a stick G, a portion of which is shown in detail in Fig. 15. The stick comprises a body portion 188, and two end sections 188*, which are pivotally connected with the body section through the medium of pins 189. The bodysection of the stick is adapted to carry clamps or clips H, adapted to receive paper after it is colored and hold the paper practically in a vertical position while it is being conducted to the drier and while it is being carried from the drier. The clips H, are adjustably secured upon the body of the stickin order that they may be moved toward or from one another to receive and properly hold sheets of different widths. The preferred form of clip is that shown in Figs. 11 and 15, comprising a shank 190, which is made to pass upward through a slot 191, made longitudinally in the stick, the upper end of the shank being threaded to receive a wing nut 192, or its equivalent. The lower end of the shank has formed upon it a jaw 193, and the upper portion of the jaw is provided with a bearing 194, in which a pivot pin 195 is jou'rnaled, the said pin serving to pivot a second and movable jaw 196. This jaw is opened upon moving the pivot pin, which is spring controlled, in one direction, the pivot pin being operated through the medium of a crank arm 197, formed at one end, or its equivalent, the spring of the pivot pin serving to normally hold the jaws in aclosed position. It is evident, therefore, that as the ends of the stick or carrier are pivotally connected with the body, and as the body is employed to carry the sheet, when the ends of the stick are supported upon guides, no matter in what position the guides may be, the body of the stick with its sheet will be free to turn and hang in such manner as to keep the sheet perpendicular; and it may here be stated that in the event it is found desirable, webbing or the equivalent thereof may be located beneath the conveyers in such a position as to receive and support the sheets, thus preventing them from buckling or curling during the process of drying.
In Figs, 21 and 22 Ihave illustrated another form of clip, designated as H, which clip may be termed a gravity clip, and comprises a yokelike body 198, having sliding engagement with the body of the stick; and at each end of the yoke a jaw 199, is pivoted, the said jaws being capable of opening upward within the yoke, in which position they separate, but when dropped downward to a horizontal position, which is their normal position, the opposing ends of the jaw will contact, if nothing is between them, and if a sheet is between them, as shown in the drawings, the sheet will be firmly held in place. In this form of clip, by pressing the sheet upward between the jaws, the sheet is fixed in position.
In Fig. 21 the entire stick or carrier is illustrated, partly in elevation and partly in section,and the guides which serve to adjustably connect the clips with the stick are designated by the reference numeral 200.
The connection between the drying section of the machine and the coloring section is effected in the following manner: The conveyer belt 186 connecting with the return conveyor belt 182 of the drier is carried upward over guide pulleys 201, located upon the forward chine; and the said belt is carried horizon-
